Cross-platform app helping Sacramento State students find campus and community resources on interactive ArcGIS maps. Led the backend/auth workstream on an 8-person capstone team with real stakeholders.

FlutterASP.NET CoreEF CoreAzure SQLArcGISJWT
  • Designed the REST API contract the whole team built against
  • Built the full-stack auth slice: Flutter UI → API → EF Core migrations
  • Hardened auth end-to-end: BCrypt, signed JWTs, server-enforced roles, secrets out of the repo
  • Live geolocation with coordinate projection to WGS84

SaaS Billing

Solo Build
2026 → +

Multi-tenant subscription billing platform built on a Spring Boot backend, React frontend, PostgreSQL, Stripe checkout and webhooks, and Supabase auth. Designed backend-first with clean layering.

JavaSpring BootReactPostgreSQLStripeDockerK8s
  • REST billing APIs on controller / service / repository architecture
  • Idempotent Stripe webhook pipeline, so retried events can't double-record
  • JWT auth (ES256 via JWKS) plus CORS for the SPA
  • Docker Compose for the full stack, Kubernetes manifests for orchestration

03 · AboutThe short version

I'm Zeke. I'm studying CS at Sac State and working toward software and cloud engineering.

Outside of class I build projects and contribute to open source. I've had two patches merged, a SQL parser fix in Apache ShardingSphere and a test suite migration in Lightly. I've been doing more with containers and cloud infrastructure lately. I graduate in December 2026 and I'm looking for software engineering, cloud, and DevOps roles.
